Statistically, most people who try to eat less fail to do it. Why do you think you don't you have the impulse to reach for a donut each time you're inconvenienced?

I guess it's more comfortable to just call them lazy, but it's utterly useless and un-actionable at a societal and personal level. Diets have to be all about managing the sensation of hunger while maintaining such a caloric deficit. CICO amounts to "Just eat less lol"
